In most cases, replacing defective CXA-0271 (also known as PCU-P077E) may not solve the problem, because the defective CXA-0271 is cause by bad CCFL lamps. So, when replacing CXA-0271 inverter, you also need to replace 2 CCFL lamps, too.
However, the most cost effective solution will be upgrading to our LED Backlight kits. To extend LCD Screen’s life and improving its performance, upgrading to UB54 Series seems to be the best option. It is easy to install, no technical skill require, no soldering require, anyone can do it!
